Halo Mass Profiles and Low Surface Brightness Galaxy Rotation Curves.
A recent study has claimed that the rotation curve shapes and mass densities of low surface brightness (LSB) galaxies are largely consistent with ACDM predictions, in contrast to a large body of observational work. I demonstrate that the method used to derive this conclusion is incapable of distinguishing the characteristic steep CDM mass-density distribution from the core-dominated mass-density distributions found observationally: even core-dominated pseudoisothermal halos would be inferred to...[Show more]
